Q: (CNN) Last Friday, a million Russian schoolchildren watched a televised address from Russian President Vladimir Putin. "Artificial intelligence is the future, not only of Russia, but of all of mankind," Putin said. "Whoever becomes the leader in this sphere will become the ruler of the world." After seeing Putin's comments, SpaceX and Tesla CEO Elon Musk tweeted that "competition for AI superiority at national level (is the) most likely cause of WW3." Though never before stated so frankly by a head of state, Putin's views on AI are increasingly shared by national security leaders in the United States, China and around the world. As I wrote in a report published by the Harvard Belfer Center for Science and International Affairs, AI research is likely to deliver a revolution in military technology on par with the invention of aircraft and nuclear weapons. In other words, Musk is correct that each country is pursuing AI superiority and that this pursuit brings new risks.Gregory C.

On Thursday, Sessions recused himself from any investigation of the campaign and has indicated he will send a clarification note to the Senate Judiciary Committee. Sessions met with a Russian diplomat twice last year in Washington -- the same one that cost Michael Flynn his national security adviser job when Flynn failed to disclose the contact to Vice President Mike Pence. Here's the reason this is suddenly controversial: Sessions did not mention his meetings with the Russian representative during his confirmation hearing, and testified that he knew of no contacts between Russians and Trump surrogates.Danny Cevallos: Perjury charges against Attorney General Jeff Sessions are unlikelyIt would be difficult to prove willful intent to give misleading testimony, he says

Q: (CNN) If you didn't already know, Cinco de Mayo is a bigger deal in the United States than in Mexico. Here, this unofficial holiday is almost as popular as, oh, St. Patrick's Day -- which means it's unfortunately become a drinking holiday. So much so that it's been nicknamed, Cinco de Drinko and even Gringo de Mayo. Actually, Thursday, commemorates Mexico's victory against the French during the Battle of Puebla in 1862, and according to research by UCLA professor David Hayes-Bautista, it isn't a Mexican holiday at all but rather an American one created by Latinos in California during the Civil War.Cinco de Mayo commemorates Mexico's victory against the French during the Battle of PueblaMany confuse the celebration with Mexican independence day, which is September 16The holiday isn't widely celebrated in Mexico
